| Abstract: | Spraying rare earth solution of 0.02% concentration can promote growth of the black locust. Average height growth was increased by 16-22%. The basal diameter growth and the average basal diamether growth was increasef by over 28%. In 3-7days,chlorophyll content increased by more than 11%. With the advantage of low cost and obvious effects, it can be used in large scale of extention. |
